Embodiment 1

[0081] In this embodiment, the distribution subscribed data communication method for smart coal-fired power plants requires software and hardware to cooperate, and the specific work components include sensors, controllers, PowerLink Industrial Ethernet, basic control software platforms, and Rabbitmq messages. Part.

[0082] Specifically, engineers perform hardware configuration on the basic control software platform, and establish a corresponding relationship with the logic measuring point on the software platform through the KKS coding and the physical testing point of the production site; after the engineer conducts logical configuration, it is dragged basic functions. The block method is combined into a specific control algorithm for each function block configuration to operate in the controller after compiling, the output signal generated by the control algorithm will trigger a corresponding operation of the production equipment; engineer The screen configuration is configured...

Abstract

The invention discloses a publish-subscribe-based data communication method for intelligent coal-fired power plants, which distributes the real-time production data of the power plant to the monitoring screen of the operator station in the form of publish-subscribe, ensuring that each operator station will only receive The data that needs to be displayed on the monitoring screen currently opened by the operator station will not generate data redundancy. With the support of RabbitMQ message middleware for data publishing and subscription mode and the realization of data publishing and subscription through some custom rules, the use of RabbitMQ message middleware can greatly improve the data throughput rate and further improve the data transmission rate, ensuring data security. real-time. The invention can greatly reduce the data redundancy in the data transmission process of the current large-scale thermal power generation site, and satisfies the real-time requirement of the large-scale thermal power generation site operators for the monitoring data in the monitoring screen.

Description

Technical field [0001] The present invention relates to the field of production control system for large coal-fired power plants, and involving a data communication method, in particular, to a distribution subscribed data communication method for smart coal-fired power plants. Background technique [0002] At present, in the field of fire power generation, fire power plants use decentralized control system DCS (DistributedControl System) to control the production process in the field. The software platform used in the DCS is an important part. A core function of the software platform is real-time data monitoring function (data monitored on real-time refresh monitoring screens, power plant staff through the monitoring screen real-time understanding of the production of power plants status). Implementing data communication requires hardware and software collaborative work in power plant production site. At present, the data communication mode of the control system of power plants i...
